Two Ordovician Conodont Faunas found with Zonal Graptolites

The conodont faunas treated in this paper are from the zone of Didymograptus balticus in South-Central Sweden and the zone of Climacograptus wilsoni in SW Scotland. On conodont evidence, the Didymograptus balticus zone is correlated with limestone strata intermediate between the Lower and the Upper Planilimbata Limestone. The conodont fauna of the Climacograptus wilsoni zone is described and figured, but no new species is named.
